This invention relates to doughnut cutters.

In the production of doughnuts there are two distinct kinds of doughnuts as recognized by the trade. The first comprises doughnuts produced entirely by machine methods in which a specially prepared doughnut mix is placed in the doughnut machine which forms a dough, kneads dough and this extrudes or otherwise feeds 'out ringshaped pieces of dough into fat to be cooked.

The second tirely by hand methods in which consists of doughnuts produced endiiferent grades of, flour are used, kneading is effected by hand and more carefully carried on,

and then ringshaped pieces of such dough are cut by hand and placed in fat.

The latter type of have been accepted as the doughnut is well known to preferred product as is evidenced by the fact that hand cut doughnuts sell at a retail price twenty to duced doughnuts.

The more immediate reason doughnut machines flour mixes, they do not effect a which greatly determinesv the doughnut and with the addition ingredients, the form of of dough is diflicult shaped doughnuts are produced.

With hand methods more and the dough is rolled to desirable consistency can ring-shaped pieces then cut.

above, with some very desirable cult to maintain a true shape pieces.

thirty per cent more than the price commanded by machine profor this is that require special doughnut proper kneading quality of the of other desired the ring-shaped pieces to maintain and poorly kneading is attained a point where the most be ascertained and the As pointed out flours it is dimfor better maintained and these iiours used.

The increased cost of hand cut doughnuts is also partly due to the limited number of dough- 40 nuts which can be produced by hand cutting methods.

The present cutter preserves all of the preferable quality of hand cut doughnuts and at the same time so greatly increases the production, of doughnuts from hand paring favorably w1th machine Briefly.

kneaded dough that they can be sold on a production basis comproduction.

the present device cuts'a large num- ,ber of ring-shaped pieces of dough simultaneously from a rolled out mass of dough, excess o dough fragments are then knocked out, and thereafter the ring-shaped pieces of dough are dropped out upon a screen for immersion in fat.

The principal object of my invention therefore is an improved doughnut cutter. l Another object is a cutter of this class which (CL IWI-4'!) A produces a plurality' ofv trimmed ring-shaped the dough' In hand cutting, true shape can be much.

pieces of dough and disposes them upon a screen or other desirable surfaces.

Still another object is a cutter greatly facilitating the cutting ofhand rolled dough andin- 5 creasing the production of same.

` Other objects and novel features comprising theconstruction and operation of my invention will appear as description of the same progresses.

In the drawing illustrating my invention:

Fig. 1 is a fragmentary bottom plan view of my improved doughnut cutter.

Fig. 2 is a. top plan View of the cutter with broken 4away portions more clearly illustrating the multiple plate construction. 1

Fig. 3 is a cross section taken of Fig. 1; and- Fig. 4 is a detail view illustrating in cross section a single cutting unit and ejector ring.

\ Referring more in detail to the drawing, l0 in- 20 dicates a base plate upon the under side of whichis solidly fixed a plurality of cutting members more clearly shown in Fig. 1. 'I'he cutting members comprise inner and outer cylinders II and I2 respectively provided with lower sharp- 25 ened edges I3 and I4 and these cylinders may be arranged in any desired manner and be of any number to comprise as many dozen cuts as required. One arrangement may be such as that on the line 2-3 shown in Fig. 1 where the cylinder units occur 30 the lower extremity thereof by means of screws 35' I1. Rods I6 are received through plate III in openings I8 with 'two rods being provided for each ejector ring and each rod supports at its upper extremity a plate I9 being fixed thereto by screws 20.

Disposed adjacent the under side of the ejector ring plate I9 is a second plate number 2l whichis freely received cverthe rod I6". Located between plate IIl and plate 2| there may be provided springs for maintaining the two mem- 45 bers in spaced relationship as for instance by thecoiled Isprings 22 shown in Fig. 3. Ihe action of these springs tends to maintain plate I9 as well as plate 2| away from platel.

Secured to plate 2l at one extremity are a 50 plurality of rods 23 which are freely received through plate III in openings 24 and aflixed to the lower ends thereof are circular ejector plugs 25 which extend into the bottom of the smaller cylinders Il.

For each cylinder unit as I I and |2 a corresponding ejector plug and rod unit similar to that described may be provided.

Also secured to the s ejector rod members 26 l maintained by screw bolts 29.

and 2l. Plate 2l is annularly recessed as shown at 3l in Fig. 2 sothat the fingers may engage the next underlying plate Il and plate I9 is similarly annularly recessed at 3| so that plate 2| may be engaged independently oi' plates I8 and 2l. In operation a mass of dough 22 is rolled out to a desired thickness after having been properly kneaded and the cutting machine is pressed ilrmly down upon the dough. The cutter is then picked up carrying cut dough, and plate 2| is then pressed inward against plate I0 whereby ejector plugs and 21 push out excess fragments ot dough 23 and 24 shown in Fig. 4 which occur 25 Just under these plug members.

Plate 2| is then allowed to spring back against plate I9 and both the multiple elector plate principle and associated plugs.

Having thus described my invention, what I claim is:

i and said base, ejector rings solidly secured to the lower extremity of the rods, and means for pressing either one or both of said ejector plates against the base.
